A testing device (10) and method and a control system (20) and method. The testing device (10) comprises a control module (101) and a performance parameter testing module (102), wherein the control module (101) is arranged to acquire a target drain current I of a power amplifier (201), which is to be tested currently, control a grid voltage of the power amplifier (201) to enable an actual drain current IO of the power amplifier (201) to match the target drain current I, and send a test notification to the performance parameter testing module (102); and is arranged to acquire, after the test of the performance parameter testing module (102) is completed, the next target drain current I of the power amplifier (201) until all the target drain currents I are acquired; the performance parameter testing module (102) is arranged to test the performance parameter of the power amplifier (201) according to the test notification. The control system (20) comprises: a receiver (202) is used to judge the quality of a signal output by the power amplifier (201), according to a correlation between the drain current of the power amplifier (201), obtained through a test, and the performance parameter, adjusting the drain current of the power amplifier (201) until the quality of the signal output by the power amplifier (201) achieves an expected value, and at the same time, the drain current of the power amplifier (201) is ensured to be the lowest, thereby achieving the balance between the performance and the efficiency of the power amplifier (201). |
